A still video camera which eliminates possible erroneous erasure of a picture image recorded in an internal memory of the camera. The camera has an image pickup apparatus and a recorder for recording a picture image signal obtained by the image pickup apparatus into a record medium which may be an internal memory or a removable IC card. Further, the camera has a manually operable switch and a protect signal recording apparatus operable in response to the operation of the manually operable switch for recording a protect signal into the record medium. The protect signal will inhibit the erasure of a picture image signal recorded in the record medium. The camera also has a controller for inhibiting erasure of a picture image signal at a portion of the record medium corresponding to the protect signal.

14. A still video apparatus as claimed in claim 10 , wherein said controlling means inhibits re-recording of a picture image into a portion of the record medium corresponding to a protect signal recorded in the record medium.
15. A still video apparatus as claimed in claim 10 , wherein said protect signal recording means records a protect signal when recording of a protect signal is instructed during a predetermined time after counting of time is started in response to starting of recording of a picture image into the record medium.
16. A still video apparatus as claimed in claim 10 , further comprising picture image reproducing means, and wherein said protect signal recording means records a protect signal when recording of a protect signal is instructed during a predetermined time after counting of time is started in response to starting of reproduction of a picture image from the record medium by said picture image reproducing means.
17. A still video apparatus as claimed in claim 10 , 15 or 16 , further comprising selecting means for selecting a protect mode or a non-protect mode, and protect instructing means for instructing recording of a protect signal in response to operation thereof in a protect mode selected by said selecting means.
18. A still video apparatus as claimed in claim 10 , wherein a reproduction of a picture image being protected is possible in a condition in which erasure of a picture image is not instructed.
19. A video camera comprising: an image pickup device; a mode definition switch that enables a user to selectively set said camera in a first mode and at least a second mode; a recorder which records a picture image signal obtained by said image pickup device onto a record medium; a manually operable switch; protect signal recording means, operable in response to an operation of said manually operable switch when said camera is in said first mode, for recording into a predetermined portion of the record medium a protect signal to inhibit erasure of a corresponding picture image signal recorded on the record medium; controlling means for inhibiting erasure of a stored picture image signal recorded on said record medium when said stored picture image signal corresponds to a detected, recorded protect signal; reproducing means for reproducing a stored picture image; and an indicator on which information representing whether a picture image reproduced by the reproducing means is inhibited from erasure is indicated when said camera is set in said second mode.
20. A video apparatus comprising: a mode selection switch which sets an operational mode of said apparatus, wherein said operational mode comprises one of at least a protection mode, a reproduction mode and an erase mode; a recorder which records an input picture image signal obtained by an image pickup device onto a record medium; protect signal recording means for recording onto the record medium a protection signal when said apparatus is in said protection mode, wherein each recorded protection signal corresponds to a recorded picture image signal; controlling means for inhibiting erasure of a recorded picture image signal having a corresponding recorded protection signal; reproducing means for reproducing a recorded picture image when said apparatus is in said reproduction mode; and an indicator, in correspondence with said reproducing means, that indicates whether a reproduced picture image has a corresponding protection signal that inhibits erasure.
